Mike writes "Here's a brilliant idea for biofuels: rather than filtering used fry oil for use in vehicles, why not simplify matters and use it to heat and power the restaurant itself? The VegaWatt turns used vegetable oil into clean heat and energy for restaurants, eliminating the dirty and costly mess of oil disposal while producing 10-25% of the electricity needed to run a small restaurant. It also produces fuel free of chemicals or fossil fuels, unlike standard biodiesel."
